It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-25068 in the wild and no public exploit code.\n\nAffected product: alsa-lib. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-25068/ (Markdown: https://insights.sbomify.com/CVE-2026-25068/index.md)","id":"CVE-2026-25068","markdown":"https://insights.sbomify.com/CVE-2026-25068/index.md","name":"CVE-2026-25068","record":{"aliases":["AZL-75773","AZL-76295","BELL-CVE-2026-25068","DEBIAN-CVE-2026-25068","DLA-4469-1","ECHO-ec6a-fa2d-8cab","GHSA-x6vq-264g-8wcx","OESA-2026-1582","RHSA-2026:7401","UBUNTU-CVE-2026-25068","USN-8044-1","USN-8044-2"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ALSA audio library","requires_auth":"none","summary":"A heap-based buffer overflow in alsa-lib allows attackers to cause a denial of service via a crafted topology file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"alsa-lib versions 1.2.2 up to and including 1.2.15.2, prior to commit 5f7fe33, contain a heap-based buffer overflow in the topology mixer control decoder.
